how to read this
This is not a directional bet. 3 wallets put $149K into Carlos Alcaraz at around 93¢ — an outcome the market already priced as all but decided. The trade on offer here is the last few cents of the dollar, not a call on the result, and reading it as smart-money conviction would be wrong.
It is also mostly one actor: the largest wallet is 72% of the buy flow ($107K), so this is a single desk parking money rather than a crowd doing the same trade.
The market has since converged — Carlos Alcaraz last traded at 99.9¢ on 2026-08-31 — so this page is a record of how large wallets positioned while the question was still open.
